So, what the difficulty bomb is going to do is that it will increase the difficulty by such an exponential amount without adjusting it that it will take more and more time to solve the cryptographic puzzles. Eventually, it will become near impossible to mine on the chain.

Will this be utilized in Metropolis? The difficulty time bomb is supposed to explode at the end of but it looks like it has been delayed by a year and a half. However, with Metropolis, the development team has made two changes that will smooth the process over to POS. Casper will be applied and as mentioned above, every th block will be mined via proof of stake. The mining reward is going to decrease from 5 ether to 3 ether. The goal is to get the entire network used to Proof of Stake protocol and to iron out all the issues before fully utilizing it in Serenity.

What are smart contracts? Smart contracts are how things get done on ethereum. The idea is simple. Imagine A and B getting a transaction or a function done without the intervention of a third party. This is a rough analogy to help you understand how it works.

So, what are the innovations that ethereum is bringing along to make their smart contracts better and more easy to develop? Suppose A gives B a smart contract to execute. The gas price chart looks like this: Image courtesy: Etherscan Now, while bitcoin usually spends the same computational power for all transactions, ethereum can vary the computational power required for each of its contracts.

Each contract has its own gas limit which is set by the contract giver. This can lead to two scenarios: The gas required is more than the limit set. The gas required is less than the limit set. During a contract execution if one wishes to go back to an earlier state during the execution, it would require manual triggering of an exception eg. The unused gas will be refunded to the contract creator. Abstraction means that anyone can use any system or protocol without completely knowing the ins and outs and all the technical details.

You simply press on the screen to activate an app, or press on the call button to call someone. Abstraction makes a complex technology accessible to the masses by removing the complexities. Abstraction is what ethereum plans to achieve in the future. As part of abstraction, ethereum is planning to blur the line between its two accounts. Ethereum, as of writing at least, has two accounts. One is the external account, the one controlled by keys that most users are aware of i.

Then you also have the contract account aka the smart contract code in the blockchain. The idea is to essentially allow users to define their external accounts in the form of a smart contract. Once this is done, the codes backing the keys can put their own unique spin on the transactions backing the code.

How does that help? As you may be aware that Quantum computing is fast becoming a possible threat to the cryptography which makes the cryptocurrencies. So suppose you want to save your transactions from a quantum attack by a malicious attacker, what can you do about it? With account abstraction, you can use signature schemes like hash ladders to define your own account which has a possibility of being quantum proof.

Your accounts can now be customizable quite like a smart contract. What are Byzantium and Constantinople? What do they mean? Metropolis is bringing in a lot of significant changes at the same time. This is why, ethereum is launching Metropolis in two phases and both will be introduced as hardforks. These two phases are: Byzantium. After a lot of delays, Byzantium hardfork will now occur at block number ,,, or about October 17 given current block production metrics. Byzantium will introduce a lot of features.

The main ones being: Zk-Snarks. Revert and returndata. Account abstraction. It is not clear when Constantinople will happen but it is being planned to take place in The main feature of it is to smooth out all the issues that may come up because of Byzantium and, more importantly, to introduce the proof-of-stake and proof-of-work hybrid chain. So ethereum is going to hard fork again? Will there be a third ethereum coin? Because of the Ethereum- Ethereum Classic and the Bitcoin-Bitcoin Cash hardforks, people have started to assume that all hard forks are bound to cause chain splits.

That is simply not the case. The reason why those forks split the chain was because the changes proposed the ethereum hardfork and the Segwit activation were so controversial that not everyone was on board. However, these upgrades have been unanimously agreed upon for a long time. Everybody knew that this was going to happen. The only bone of contention could be the proof-of-stake hardfork, however, the miners are not going to gain much by remaining on the old chain since, as already discussed, the difficulty bomb will make mining near impossible.

So, is the value of ether going to go up? You need to do your own research before you invest in a coin. Byzantium is bringing in so many changes to ethereum that it will be fascinating to see how things turn out. The implementation of zk-snarks is particularly game changing and of course, Constantinople with its proof of stake is going to be something that everyone in the crypto world is going to keep their eye on. The upcoming year could be absolutely revolutionary for ethereum and their dream of a decentralized future.

You can call him a serial entrepreneur with a couple of startups up his sleeve and tonnes of them in his mind. With over K subscribers on youtube, Ameer hosts his own show called ameerapproved, where he talks about entrepreneurship and shares the latest crypto market updates. He has been a contributor at HuffPost, Due. There were plenty of members of the community that respected and commended those that refused to cooperate with the hard fork. It is an ambitious goal that many have called into question.

According to its website at the time of writing, it still does not possess a block explorer, which is a bit disconcerting for any cryptocurrency in this space that wishes to receive any level of legitimacy or widespread adoption. These are the purported features, according to its website: Two-Layer Network System: Ethereum allows individuals to power their transactions via the Gas that is supplied to the network.

EtherZero eliminates this system and instead has opted to add another layer to the protocol as a means of facilitating transactions that take place on the chain through the dApps. Autonomous Community Governance System: Rather than having a centralized authority that is able to settle disputes or make overarching decisions about the future direction of the chain, there is a governance system that has a democratized means of implementing solutions.

As you most likely observed with the Bitcoin hard forks , the purpose of most forks is to provide some sort of inherent utility that the legacy chain did not possess and refused to or could not implement. The primary feature that it boasts is that individuals will be able to make instant payments to one another with shocking speed without needing to receive any sort of fee or compensation.

This design means that the miners must rely on the block reward exclusively. There are both pros and cons to such a PoW blockchain consensus structure that EtherZero will have to navigate through in the near future. Metropolis is the 3rd stage, focusing more on the scalability of the network. The four stages are: Stage 1: Frontier Stage 3: Metropolis Stage 4: Serenity With the Metropolis network, there are a number of features associated with its implementation.

The proposed features of the upgraded network are as follows: Zk-Snarks: This refers to the privacy feature used in Zclassic, which allow for greater privacy in transactions between users. Proof-of-Stake PoS : In Bitcoin, miners on the network all race to solve an algorithm in order to create the next block.

This prevents them from being a bad actor, as they will stand to lose their staked coins if it is deemed that they acted destructively. POS is also much economically-friendly, as it requires less electricity costs. The purpose of Smart Contracts is to provide a decentralized means of transactions based on the fulfilment of certain conditions that were previously agreed to between the two or more parties engaging in the transaction.

Byzantium is designed to make the Ethereum platform lighter and faster to run.
